The Cromwell Association Online Directory of Parliamentarian Army Officers

This new resource published by British History Online contains the names of over 4,000 officers who served in the armies of Parliament during the first English civil war (1642-6), and in some cases subsequently.
There is an alphabetical directory and the ability to search the full text of all the entries.
Most entries lack genealogical information.
The project to compile the information was funded and supported by The Cromwell Association.
